Our Areas of Expertise
Our team specialises in civil and infrastructure engineering, delivering safe, compliant, and durable solutions for residential, commercial, and public projects across NSW, VIC & QLD.
Stormwater Design and Management
Effective stormwater management is critical for reducing flooding, controlling erosion, and protecting properties and infrastructure. At Apex Civil Engineers, we provide comprehensive stormwater design services for residential, commercial, and industrial developments across NSW, QLD, and VIC.
Our team uses advanced hydraulic and stormwater modelling software, such as InfoWorks ICM and EPA Water Sensitive Urban Design tools, to optimise drainage networks and meet regulatory standards.
Our stormwater solutions include:
-
Stormwater drainage system design for residential subdivisions, commercial developments, and public infrastructure.
-
On-site detention (OSD) and retention systems to manage peak flows and reduce downstream impacts.
-
Water quality management including sediment and pollutant control.
-
Roof and pavement runoff management, ensuring compliance with local council stormwater regulations.
These solutions not only protect your property and the environment but also improve project approval outcomes. Learn more about our Civil Engineering Services for development projects.
Flood Risk Assessment and Mitigation
Flooding poses a significant risk to communities and infrastructure. Our engineers deliver detailed flood risk assessments and implement mitigation strategies tailored to your site. By combining hydrological and hydraulic analysis, we provide practical solutions for residential, commercial, and industrial developments across NSW, QLD, and VIC.
Our flood mitigation services include:
Flood modelling and mapping to assess hazard levels and design safe infrastructure layouts.
Floodplain management guidance aligned with state planning policies.
Site-specific flood mitigation strategies including levees, bunds, and stormwater retention basins.
Compliance and approvals assistance for local councils and state authorities.
Addressing flood risks early ensures safer communities, protects assets, and reduces liability.
Water Infrastructure Design
Efficient water management is a vital part of modern development. We provide end-to-end water infrastructure solutions to support sustainable and reliable water supply and reuse for developments in NSW, QLD, and VIC.
Our water infrastructure services include:
Potable and non-potable water reticulation design for residential and commercial sites.
Stormwater harvesting and reuse systems to reduce mains water consumption and improve sustainability.
Pump station and pipeline design, ensuring efficient flow management and long-term performance.
Integration with site infrastructure and environmental requirements, including erosion and sediment control.
These services are designed to meet both regulatory compliance and your project’s operational needs.
Frequently Asked Questions
Stormwater engineering ensures drainage systems function safely and efficiently, reducing flooding risks and improving water quality. More info: Australian Rainfall and Runoff.
Yes. Councils often require a flood risk assessment for developments in flood-prone areas. Check requirements: NSW Planning Portal.
WSUD integrates stormwater, water supply, and environmental protection into urban planning. Learn more: Melbourne Water – WSUD.
Yes. We design systems for houses, subdivisions, multi-storey buildings, commercial precincts, and infrastructure projects.
Local council stormwater guidelines
By incorporating flood modelling, levees, detention basins, and sustainable drainage, flood mitigation reduces risks to properties and infrastructure.
